THlLL-COUPLING SPECIFICATION forming part of Letters Patent No. 400,526, dated April 2, 1889. Application filed November 22, 1888. Serial No. 291,602. (No model.)

To all whom t may concern.:

Be it known that I, BRYANT E. WADE, a citizen of the United States, residing atRockford, in the county of Winnebago and State of Illinois, have invented a certain new and useful Improvement in Non-Battling Thill-Couplings for Vehicles, of which the following is a specification.

The object of this invention is to produce a non-rattling thill-coupling, by means of which thills may be quickly coupled with and uncoupled from vehiclesv Vwithout the aid of a wrench or other tool.

This invention consists of certain new and useful features of construction .and combinations of parts, hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure l is a plan view of my improved thillcoupling. Fig. 2 is a vertical partial section of the same through the dotted line X X in Fig. l. Fig. 3 is a side elevation of the thillcoupling withthe cap raised. Fig. 4. is a partial section through the dotted line X X in Fig. I of the coupling-cap. Fig. 5 isan isometric view, in detail, of the knuckle and Fig. 6 is a view of the under side of a cap that will be fully described hereinafter.

Like letters of reference indicate corresponding parts throughout the several views.`

A is a coupling-socket having end plates, A', provided with pintle-bearings A2, and slots A3 opening out of the latter.

A4L is a bearing having a vertical tubular passage, A5, extending therethrough, depending from the under side of the socket A, the Ofiice whereof will be fully vdescribed hereinafter.

B is a coupling-knuckle of proper form and dimensions to be contained in the socket A, and provided with pintles B', adapted to enter the bearings A2 in the end plates, A', through the slots A3 therein of said socket.

B2 is a thill-iron integral with the knuckle B, and secured to the thill B3 by means of a T-bolt, B4, and nut C is a fore-axle clip integral or rigidly connected with the socket A, and provided with a clip-tie, C', and nuts C2, all of which parts are too Well known to require further description.

D isv a coupling-socket cap having end plates, D', provided with curved recesses D2 in their inner faces adapted to admit the free ends of the pintles B' and furnish upper bearings, D, for the saine. The socket-cap D is hinge-jointed to the rear end of the socket A by means of a pintle, D4.

D5 is a cylindrical recess sunk in the under side of the cap D and threaded to receive a part to be described hereinafter.

E is a set-screw for holding the cap D securely down over the knuckle B in the socket A. Theupper end of the set-screw E is provided with a thread, E', to adapt it to engage with `the inside of the recess D5 in the cap D.

E2 is a cap having a circular opening, E3, therein to admit the set-screw E therethrough, and provided with radial grooves E4, to prevent said set-screw from working loose.

lE5 is a washer of some yielding substance, preferably rubber, included in the cap E2, and perforated centrally to admit the set-screw E therethrough.v Theofdce of the washer E5 is .to allow by its elasticity a little upward motion to the cap D, and to prevent the parts secured together by means vof the set-screw E from rattling.

E is a washer, which prevents the set-screw E and its attachments from becoming detached from the socket A when the cap D is released for the purpose of uncoupling the thills B2.

To couple the thills, I raise-the cap D to the position shown in Fig. 3, and introduce the knuckle B into the socket A, and the pintle B' into the bearings A2 om the slots A2. N ext lower the cap D and turn the set-screwE until the coupling will not rattle. Reverse the operations just detailed to uncouple the thills.

I claim as new and desire to secure byLetters Patent l. In combination, the coupling-socket A, having end plates provided with pintle-bearings A2, and slots A3 opening out of the latter, and a bearing, A4, having a tubular passage therethrough, a couplingknuckle of proper form and dimensions to be contained in said socket A, and provided with pintles B', adapted to enter the bearings A2 in lthe IOC end plates, A', through the slots A therein, a

thill-iron integral with said knuckle, a Coupling-socket cap having,` end plates, D', provided with Curved recesses D2 in their inner 5 faces, adapted to admit the free ends of the pintles B and furnish upperbearings, D3, for the same, said eap also havingr a threaded recess, D, therein, and being hinge-jointed to the coupling-socket A, and a set-screw inserted through the passage in the bearing A* into the recess D5'in the eap D, and securing all of the aforesaid parts together to prevent them from rattling', substantially as set forth.

clip C, with its tie C', substantially as dezo scribed, and for the purpose set forth.

BRYANT E. lVADE.
